Bending nanoribbons tunes diamond's light emission without doping
In a new Physical Review Letters study, researchers have demonstrated that bending diamond nanostructures can tune the light they emit without doping.
Page 2: Research news on Spectroscopy
Spectroscopy is an analytical technique that measures the interaction between electromagnetic radiation (or other energetic probes, such as electrons or ions) and matter as a function of wavelength, frequency, or energy to obtain information about a system’s composition, structure, and dynamics. By monitoring absorption, emission, scattering, or reflection, spectroscopy reveals quantized energy levels associated with electronic, vibrational, and rotational states. Variants such as UV–Vis, infrared, Raman, nuclear magnetic resonance, and X-ray spectroscopy exploit distinct interaction mechanisms and selection rules, enabling determination of molecular identity, chemical environment, bonding characteristics, and in some cases spatial or temporal evolution of materials and biochemical systems.
Testing tiny telescope robots reveals design changes that could improve galaxy maps
Astronomers have cataloged billions of stars and hundreds of billions of galaxies. We have found thousands of planets orbiting stars. We can also map where galaxies sit and trace how the universe changes over time.

Researchers build microscopic DNA 'sails' to pull molecules apart
Across every cell in the body, molecules are constantly pulling, gripping and releasing under mechanical strain. That force often decides whether a drug sticks to its target, whether a cell holds its shape or whether a disease ...
